Nuclear Structure Studies with the7Li(e,e′p)Reaction

Abstract

Experimental momentum distributions for the transitions to the ground state and first excited state of {sup 6}He have been measured via the reaction {sup 7}Li( e,thinspe{prime}p){sup 6}He . They are compared to theoretical distributions calculated with variational Monte Carlo (VMC) wave functions which include strong state-dependent correlations in both {sup 7}Li and {sup 6}He . These VMC calculations provide a parameter-free prediction that reproduces the measured data, including its normalization. The deduced spectroscopic factor for the two transitions is 0.58{plus_minus}0.05 , in perfect agreement with the VMC value of 0.60. This is the first successful comparison of experiment and {ital ab initio} theory for spectroscopic factors in p -shell nuclei. {copyright} {ital 1999} {ital The American Physical Society}
